  2. 1. Evaluation of Gasoline PPC in a Multi-cylinder Engine : Capabilities & Challenges

    Author : Nikolaos Dimitrakopoulos; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Partially Premixed Combustion PPC ; Light duty engine; Efficiency; Gasoline Compression Ignition; renewable gasoline;

    Abstract : Internal combustion engines have been the most used engine design when it comes to vehicle propulsion and transportation. But as the number of vehicles increase, new problems arise as well. READ MORE

  4. 2. Supra-threshold hearing loss and wide dynamic range compression

    Author : Henrik L Olsen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Hearing impairment; compression; hearing aids; modulated noise; speech intelligibility; temporal resolution; modulation transfer function;

    Abstract : Cochlear hearing loss leads to deficits in many perceptual aspects, including threshold elevation (loss of sensitivity), reduction of auditory dynamic range (loudness recruitment) and problems with resolving sounds (loss of supra-threshold hearing). An ongoing debate is whether assessment of the individual supra-threshold hearing provides information which is likely to have an important influence on clinical decisions on signal processing strategies.

  5. 3. Essays on contracts and social preferences

    Author : Robertas Zubrickas; Handelshögskolan i Stockholm; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : This thesis deals with the problems of optimal grading, employee performance evaluation by unaccountable managers, and the evolution of inequity-averse preferences. The purpose is to explain certain stylized facts related to these problems, and this is attempted with the help of contract-theoretic models. READ MORE

  6. 4. Design of High Linearity MMIC Power Amplifiers for Space Applications

    Author : Oliver Silva Barrera; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pHEMT; GaAs; reliability; Power amplifier; non-linear modeling; Junction temperature; C-Band; Infrared measurements;

    Abstract : The high linearity performance in satellite transmitters is receiving increasing attention due to the demands of higher data rates in satellite communication links. During the last decade, digital communication links in satellite system have been replacing the previous analog links increasing the channel efficiency by allocating multiple carriers in the transponder bandwidth.

  7. 5. A digital filterbank hearing aid

    Author : Thomas Lunner; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Digital signal processing hearing aids may provide possibilities for new signal processing strategies to compensate for hearing loss. However, to be practically usable in a headworn hearing aid the digital circuitry needs to fulfil requirements of low power consumption, low supply voltage and small size. READ MORE
